I found out constipation could be due to lack of minerals in my body. Many folks (like myself) don’t have consistent access to mineral water. I can find it at Moms Organic 40 mins away from my house and it’s expensive. Mainly I drink filtered tap water. I bought these Mineral drops and I have gone once a day, and it’s not painful at all since I started using. I have a sensitive stomach, so I decided to under-dose. To start out, I put 10 drops in my Brita Filter (holds 10 cups). Next day I did 15 drops. Thankfully no nausea! I hope it helps you too!!
